Specification of Letters Patent.

Patented Aug. 22, 1911.

Application filed April 22, 1911. Serial No. 622,675.

To all whom it may concern:

Be it known that I, RAY It. Sanonnson, a citizen of the United States, and a resident of Orr'ville, in the county otWayne and State 01 Ohio, have made certain new and useful Improvements in Drilling Devices, of which the following is a specification.

l t 1y invention relates to lIHP'LOVGIHOHtLS in drilling machinery, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object 01 my invention is to provide a device of the walking beam type in which the rapidity of the oscillations of the drill rod may be considerably increased without sacrificing its effectiveness in any particular, thereby rendering the machine capable of doing more work in a given time than the ordinary drilling device.

A further object oi my invention is to provide novel means for operating the drill rod.

Other objects and advantages will appear in the following specification, and the novel features oi the device will be particularly pointed out in the appended claims.

My invention is designed to be an improvement over that disclosed in my prior Patent #993,882 of May 30, 1911.

My invention is illustrated in the accompanying drawings forming part of this application in which- Figure 1 is a side elevation showing one embodiment of my invention, Fig. 2 is a plan view of the device, Fig. 3 is an end view oi a portion or the device, and Fig. l is a detail view showing the connection of the crank with the upper walking beam.

in carrying out my invention 1 provide a frame portion consisting of the side members 1 and 2 which are supported upon the axles 3 and 4 respectively of the wheels 5 and the front Wheels 6.

In the present application I have omitted certain parts such as the guide masts for the drill rod, which are ordinarily carried upon the truck, and I have therefore shown only the parts which are novel.

Carried upon the frame near the rear end thereof are the uprights 7 and 8. Pivotally connected to a rod 9 carried by the uprights 7 and 8 is the upper walking beam, which consists of two portions 1O and 10 These two parts are secured together toward their frontends, and are provided with rounded flange castings 11. A similar lower walking beam 12 composed of two parts precisely similar to the parts 10 and 10 is pivotally carried at 13 upon the standards 7 and 8, and its opposite end is also provided with the rounded castings 11. The two walking beams are pivotally connected together by means of a link 1 1, which is journaled at its upper end at 1 1 and at its lower end at let". The upper walking beam members 10 and 10 are pivotally connected by means of a pitman 15 with a crank 16 on a shaft 17, which bears a driving pulley 18.

Referring now to llig. l, l'. have shown therein a gear 19 which is secured to a shaft 20 hearing a grooved drum 21, the shalt being carried in suitable bearings "22 and 23. A gear 2% slidably mounted on the shaft 25 and may be shifted into and out of mesh with the gear 19 by means oi the lever 26 or by any other suitable means. The shaft 25 bears the grooved drum 27, and also a gear 28. Upon a shaft 29 is a worm gear 30 which meshes with a worm 31 (see Fig. 1) on a rod 32 and controlled by a hand wheel 32. The shaft 29 also bears a gear 3 ,1: slidable on the shalt by means of a lever 35 or by any other suitable means. The shait't 36 bears a gear 37 which may be thrown into and out of mesh with the gear 19 by means of the lever 38, or by any other suitable means. This shait't 36 also bears a worm gear 39 which meshes with a worm 10 on a rod :l-l controlled by the hand wheel 412 (see Fig. 1).

As will be seen from the drawings a rope 18 is wound around the drum 21, passes upwardly over the pulley le t; carried between members 10 and 10 ol" the upper walking beam, and thence i'orwardly where it terminates in an eye A rope el-T (see llig.

2) passes through the eye 15, one portion of the rope passing over one end oi the member 10", and the other portion passing over one end 01 the member 10. The ends ot the rope 17 terminate in eyes 17 which pass through an opening in the clamp member dB. The latter is designed to hold the drill rod 419 about which it is clamped by means oi? the bolt 50. A rope 51 wound around the drum 27, passes upwardly over the pulley 52, thence forwardly terminating in an eye 53. A rope 5 1 is hooked to the eye 5;, in the same manner as that described in connection with the rope -17, passes underneath the round castings 11 and thence upwardly terminating in eyes 545 secured in the openings of the clamp member 18.

From the foregoing description of the various parts of the device the operation thereof may be readily understood.

In operation the clamp 28 is elevated within a few inches of the upper beam and clamped tightly to the rod by means of the bolt 50. This can be quickly done by allowing the gears 24 and 19 to remain in mesh, then throwing out of mesh the gears 37 and 34 and turning the shaft 20 by means of a crank placed on the squared ends 21 of the shafts. It will be-seen that as the rope is wound on the drum 21 it is wound off from the drum 27, thereby permitting the clamp 48 to be shifted until it is within a few inches of the upper walking beam. Here the clamp is secured to the rod 49 in the manner described. The gear 37 is now thrown into mesh with the gear 19 and the gear 34 is thrown into mesh with the gear 28. The gear 24 is thrown out of mesh with the gear 19. It will be seen now that the drums 21 and 27 are controlled by the respective hand wheels 42 and 33 so that the tension on the ropes 43 and 51 may be adjusted. Power is applied through the power wheel 18, and is'transmitted by means of the pitman to the walking beams which are connected,-as stated before, by the link 14. The rod is reciprocated positively in an upward and downward direction, and as the drilling proceeds, the hand wheel 42 is turned to let ofl the rope from the drum 21 and the hand wheel 33 is turned to take up the slack of the lower rope 51 so as to keep the tension at the proper point.

If it is desired to control the tools by one hand wheel, the gear 24 is thrown into mesh with the gear 19 and the gear 34 is thrown out of mesh with the gear 28. The hand wheel 42 will therefore control the unwinding of the rope from one drum and the winding of the rope onto the other drum.
